Sources: Jerry West threatened to resign over Thompson-Love deal

Jerry West threatened to resign his position as the Golden State Warriors head consultant if the team went ahead with a proposed trade last summer with the Minnesota Timberwolves involving guard Klay Thompson and forward Kevin Love, SI.com’s Chris Ballard reports.

According to Ballard's source, West believed that trading Thompson away would be a mistake, because the Warriors were a defensive team and Love was not primarily known for his defense.

According to the Bay Area News Group, Thompson’s father, former NBA player Mychal, said that Warriors owner Joe Lacob and general manager Bob Myer wanted to make the trade, but West and head coach Steve Kerr vetoed the deal.

West has been with the Warriors since 2011 after executive stints with the Memphis Grizzlies and Los Angeles Lakers.

Love ended up being traded to the Cleveland Cavaliers in August as part of a three-team deal with the Philadelphia 76ers that sent 2014 No. 1 overall pick Andrew Wiggins, 2013 top pick Anthony Bennett and 76ers forward Thaddeus Young to Minnesota. Philadelphia received a 2015 first-round draft choice from the deal.

Love played 75 regular games this season with the Cavaliers and averaged 16.4 points and 9.7 rebounds. Love dislocated his left shoulder in the first round playoff series against the Boston Celtics and has missed the rest of the team’s run to the NBA Finals.

Thompson had his best season in 2014-15, averaging 21.7 points a game and earning his first All-Star Game selection as well as All-NBA third-team honors.

On May 28, 2014, Jerry West, a model of brilliant basketball nicknamed "The Logo" for being the silhouette sandwiched between red and blue on the NBA's emblem, turned 76 years old. Also nicknamed "Mr. Clutch" for his knack for coming through when it mattered most, West led the Lakers to the NBA Finals nine times in his prolific 14-year career. He averaged 31.0 and 31.3 points in 1964-65 and '65-66, respectively, and tallied 25,192 points (the most in Lakers history) and 6,238 assists (second). West made a pretty good G.M., too, helping bring Kobe and Shaq to the Lakers.
